SPRINKLER-HEAD No. 920,592. Specification of Application filed May 25,

To all whom it may concern:

Be it known that I, TALBOT LENNOX, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Sprinkler-Heads, of which thefol lowing is a full, elear, concise, and exact description, referencebeing had to the accompanying drawing, forming a part of thisspecification.

Hy invention relates to sprinkler heads for sprinkling carts or cars.

It has for its object to provide means whereby the water may be thrownat a great distance on either side of the cart without causing the waterto ilow with such iorce as to tear up the ground.

The present method of sprinkling the streets on either side of railroadtracks has serious objections in that if the water is sprayed withsufficient force to cause it to reach. to either curb of the street, thewater near the tracks will be delivered in such a volume and with suchforce as to tear up the gravel and seriously affect the road bed of thetracks. This is due to the fact that no means have been provided forvarying the spray, in order that a small spray of water be thrown nearthe tracks and a larger spr y with greater force may be thrown to extendto the curb.

By my present invention, I am enabled to regulate the spray to such adegree that the spray near the track will be comparatively small, whilethat which is intended to reach to the curb will be larger.

One device for accomplishing my object is. shown in the accompanyingdrawings, in which Figure 1 is a front elevation of the sprinkler head;Fig. 2 is a side elevation thereof; Fig. 3 is a sectional view, taken onthe line '22 of Fig. and, Fig. 4 is a detail view of the means forcutting oil the water supply in the sprinkler head.

is shown in the accompanying drawings, I provide a cup-shaped casing orhead 1, having the rearward extension 2 into which is adapted to bescrewed or otherwise connected a pipe or hose 3 leading from the watersupply. Formed around one-half of the periphery of the head or casing isa groove 4 adapted to receive a rubber or resilient pack- LettersPatent.

ing 5. A cover 6 for said head or casing is provided with a groove 7extending half-way around the same, in which is adapted to fit the outerend 8 of the casing, and a second groove 9 is formed on said cover, alsoeX- I tending half-way around the same, which cooperates with the groove1 in forming a channel for the reception of the rubber gasket 5. By thisarrangement a slot or opening 10, as shown in 1, is formed, whichextends only half-way around the sprinkler head, causing a flat spray ofwater to issue from one side only thereof. Projecting from the lowerportion of the cover 6 is one portion 11 01" a hinge, which, whenconnected with the other portion 12, forms a hinge joint between thecasing or head 1 and its cover 6. By hinging the cover 6 to the head, asshown, the slot or opening formed by opening the cover will assume aV-shape, as shown in Fig. 1, and a spray will be formed, which is largerat one point as it issues from the sprinkler than at another. The innerwall 13 of the groove 7 has secured thereto a washer 14, which preventsthe water from working ut between the casing and the wall 13.

For controlling the amount oi water which issues from the slot oropening 1.0, a valve 15 is provided. The valve 15 comprises a cupshapedhead 16, which is adamed to fit with in the cover 6, as shown in Fig. 2.T he side wall ol' said head is provided with a slot 17, which willregister with the slot 10 and permit the water to flow, but when thevalve is turned until the portion 18 is in front of the opening, 10, thewater will be e'llcctually cut ofi. Also it will be noted that byturning the valve 15, the water may be delivered to predetermined pointsas, for instance, by cutting off the delivery of the water 'lI'OIH thelower end of the slot, the water will be only delivered to the curb andby cutting off the water at-the upper end or the slot in the sprinklerhead, the water will be delivered near the tracks and will not bedelivered to the curb. A stem 19 01 said valve is suitably journaled ina bearing 20, formed in thehead 6, and upon the outer end of said stemis keyed a sprocket wheel 21 for turning the valve to open or close theopening 10. For controlling the size of the spray, two upwardlyextending arms 22 are formed upon the upper portion of the head 6,between tends across the head or casing and is journaled in the bearings24 formed on the casing 1. A sprocket wheel 26 is screwed upon the bolt23 and is mounted between the bear ings 24 and 25, whereby, as the wheelis turned, the bolt will be moved laterally one way or the other,thereby opening and closing the slot as desired. I preferably mount fourof these sprinkler heads upon a sprinkling car and said heads arearranged with the slot 10 at an angle of forty-five degrees, as shown inFig. 1. By this arrangement, it will be seen that the upper part of thespray will describe a parabolic curve and thus have a maximum range andstrike the ground substantially normal without much damage by washing orsweeping effects. The water will thus be thrown into the center of thetrack and over to the curb, thereby sprinkling the entire street. Thegraduated slot is so arranged that from the smaller end the water forthe tracks is adapted to flow and from the larger ends the spray orwater for the street is adapted to flow, which eifectually prevents thedelivery of a larger volume of water from flowing with great forceimmediately upon the ground and thereby prevent the washing out of thetrack bed.

It will be seen that by my invention I am enabled to provide a sprayingopening in the sprinkler head, which is comparatively small at one pointand gradually increases in size, thereby throwing a graduated spray,which will sprinkle a large area of ground without throwing the water insuch a volume near the car or cart as to tear up the roadway.

While I have shown and described one means for accomplishing the variousobjects of my invention, it will be understood that I do not wish tolimit myself to this particular construction, as there are variouschanges which may be made without departing from the spirit of myinvention, the principal feature of which is to deliver a spray of waterwhich is substantially V-shaped in cross section.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:
